central point dominance: filter not found error

graph-tool
1

Hi everybody,
I do not understand how to use the --central-point-dominance.
I have a small undirected graph (a chain) in a file grafo.dot

graph G {
1 [VERTEX_BETWEENNESS="0"];
2 [VERTEX_BETWEENNESS="0.285714"];
3 [VERTEX_BETWEENNESS="0.47619"];
4 [VERTEX_BETWEENNESS="0.571429"];
5 [VERTEX_BETWEENNESS="0.571429"];
6 [VERTEX_BETWEENNESS="0.47619"];
7 [VERTEX_BETWEENNESS="0.285714"];
8 [VERTEX_BETWEENNESS="0"];
1--2 [EDGE_BETWEENNESS="0.333333"];
2--3 [EDGE_BETWEENNESS="0.571429"];
3--4 [EDGE_BETWEENNESS="0.714286"];
4--5 [EDGE_BETWEENNESS="0.761905"];
5--6 [EDGE_BETWEENNESS="0.714286"];
6--7 [EDGE_BETWEENNESS="0.571429"];
7--8 [EDGE_BETWEENNESS="0.333333"];
}

The following command:

$graph-tool --undirected --load
grafo.dot --central-point-dominance="VERTEX_BETWEENNESS|-"

graph-tool error: graph filtering error: filter not found

$graph-tool --undirected --load grafo.dot --central-point-dominance

Usage: /usr/local/bin/graph-tool [options]

graph-tool: error: --central-point-dominance option requires an argument

$graph-tool --version:

graph-tool 1.1.2 (r111)

(configured with ./configure --disable-visibility)
$gcc -v

gcc version 4.1.2 (Ubuntu 4.1.2-0ubuntu4)

$uname -r

2.6.20-16-386

Any suggestion?
Cheers,
Andrea

This is a bug in graph-tool. I'll fix it in the git repository shortly.
As a temporary workaround, you can simply run the command on a directed
graph, which will have the same result as the undirected, as such:

$ graph-tool --undirected --load grafo.dot --directed
--central-point-dominance="VERTEX_BETWEENNESS|-"
# central point dominance (VERTEX_BETWEENNESS):
0.272109428571

Thanks for pointing this out!

Cheers.

Thank you Tiago for this workaround (and for this software that is really
really nice).

You're welcome. :slight_smile:

It may interest you to know the bug in question was just fixed in the

Hi,

This is really a beginners question :slight_smile: sorry, but I haven't used version control before...

I've got graph-tool-1.1.2 installed on ubuntu 7.10 (compiles with no problems), but would like to upgrade to the latest development source code.

I've installed git and typed
git clone git://git.forked.de/graph-tool

git run without errors and I found a directory ./graph-tool/ with some, but not all, files needed to install.

What do I do next? I tried to replace the old graph-tool source files with the new ones and re-compile, but make failed, so I guess this is the wrong thing to do...

Many thanks,
Rui
